My neighbors are giving me a hard time about my dog barking. Personally I don't mind it. What can I do to stop the barking?

I have a 3 year old weim and my neighbors are giving me a hard time about his constant barking when he is in the back yard. Now, I don't really have a problem with his barking. I like a vocal dog. It makes me feel better when I am not at home to have a loud dog that distracts burglaries.. etc. I think it is safer for my family. However, back to the neighbors. I remember the way that we used to stop dogs from chasing cars by throwing a bucket of water out of the car. Would that work for the dog if I threw a bucket over the fence or is there a better remedy? I don't want to completely silence the dog, but I do need to get the barking under control. Any advice you could give me would be helpful.

Thanks,
Charley
